Uni-Sil XS 0020

  • $128.00


Our new Uni-Sil is a universal casting silicone that is formulated to be extra soft (XS) and low viscosity. This silicone was formulated primarily for casting applications such as medical simulators, dolls, masks, and prosthetics. UniSil has a 40 minute working time and a 2 hour demold time.

Like our other translucent SPFX silicones, Uni-Sil may be pigmented to simulate organic tissue using our silicone pigments and flocking.

Properties unique to Uni-Sil:

  • Easy to pour. Uni-Sil is VERY low viscosity to allow for long pour time when casting into complicated molds.
  • May be thickened. Uni-Sil is very low viscosity but can still be thickened with TinThix thickener for brush-on applications such as patching and seaming on masks or cast parts.
  • Relatively fast demold. Despite its long working time, Uni-Sil may be demolded in 2 hours allowing for fast turn-around time in production.
  • High tear strength. Most mask applications will not require any reinforcement fabric.
